Abstract
Presented are systems and methods that change the order in which triangles are rendered, to improve post-transform vertex cache efficiency and reduce view-independent overdraw. The resulting triangle orders are orders magnitude faster to compute compared to previous methods. The improvements in processing speed allow such methods to be performed on a model after it is loaded (i.e., when more information on the host hardware is available). Also, such methods can be executed interactively, allowing for re-optimization in case of changes to geometry or topology, which happen often in CAD/CAM applications.
